Applies to: Exchange Server 2007 SP3, Exchange Server 2007 SP2, Exchange Server 2007 SP1, Exchange Server 2007

This topic discusses items to be aware of when you migrate an Exchange Management Pack from Microsoft Exchange Server 2003 to Exchange Server 2007.

The following are configuration issues that you might encounter when you migrate to from Exchange 2003 to Exchange 2007.

There are 26 performance threshold rules that can be modified to suit the individual user's environment. Several (20) of these rules no longer exist, have been renamed, or are not relevant to a 64-bit computer. Examples of the latter would be pool non-page bytes and Information Store virtual bytes.

You might decide to manually migrate the thresholds of the remaining six rules that have similar thresholds to those in Exchange 2003.

In the Exchange 2003 Management Pack, there are 1,690 event alert rules. You may have disabled some that you did not consider relevant to your environment. In Exchange 2007, there are 1,790 event rules that can raise alerts. Some of the rules in the Exchange 2007 Management Pack are the same or similar to those in the Exchange 2003 Management Pack. You should review the rules that were disabled for Exchange 2003 and decide whether the same rule should be disabled for Exchange 2007.

The Exchange 2003 Management Pack required that users select the services they wanted to monitor for their servers. In addition to monitoring Exchange services, users could manage additional services such as antivirus services.

The Exchange 2007 Management Pack automatically monitors all services relevant to each server role. These include Microsoft Windows services such as IISAdmin. Although the Exchange 2007 Management Pack no longer lets users monitor additional services, this capability is provided by Microsoft Operations Manager (MOM). You should review the services that are not in the following list:

  • ADAM_MSExchange
  • EdgeCredentialSvc
  • IISAdmin
  • MSExchangeADTopology
  • MSExchangeEdgeSync
  • MSExchangeFDS
  • MSExchangeIMAP4
  • MSExchangeIS
  • MSExchangeMailboxAssistants
  • MSExchangeMailSubmission
  • MSExchangePOP3
  • MSExchangeRepl
  • MSExchangeSA
  • MSExchangeSearch
  • MSExchangeServiceHost
  • MSExchangeTransport
  • MSExchangeTransportLogSearch
  • MSExchangeUM
  • MSFTESQL-Exchange
  • MSSpeechService
  • W3Svc

The Exchange 2003 Management Pack has a MOM notification group named Mail Administrators. Notifications from all alerts raised by rules in the management pack are sent to members of this notification group. Users manually add MOM Operator objects that contain an administrator's e-mail address or pager number to MOM notification groups. Notification groups have no relation to Active Directory directory service groups.

When you import the Exchange 2007 Management Pack, be aware that if you use the Replace option instead of the Update option, the membership of the Mail Administrators group will be erased.

The Exchange 2007 Management Pack includes the Mail Administrators group to whom all alerts are sent. It also contains one notification group for each Exchange 2007 server role. These role-based notification groups let administrators receive notifications for only the set of servers that they are responsible for.

Users may have used the reports that were included with the Exchange 2003 Management Pack as the basis for building their own custom reports. Some of the data that may have been used in such custom reports, such as message tracking data, is no longer available in the Exchange 2007 Management Pack. Instead, users have a better option. This is to use the free reporting tool from Quest Software at http://www.quest.com/exchange_reporting_management_pack/.
